RAISING FELT-PRESS FOR PAPER-MACHINES.

Specification of Letters Patent.

Application filed January 18, 1907.

Patented May 2, 1911. Serial No. 352,999.

To all whom it may concern:

Be it known that we, FELIX BANNING and FRIEDRICH KUNKEL, both citizensof the German Empire, residing at Diiren-on-the- Rhine, Germany, haveinvented new and useful Improvements in Raising Felt- Presses forPaper-Machines, of which the following is a specification.

The raising of the wet paper of the socalled turning or raising feltpress of the paper-machine offers considerable difiiculties and is thecause of a very great deal of waste.

Figure 1 of the drawing shows the improved arrangement of the layingfelt press a a and b b and of the raising felt press of paper-machineswith several wet-presses, .in a diagrammatic view. Fig. 2 is a like viewshowing a modification.

Paper is fed into the press, as is well known, by means of endlesstransporting felt cloths e, f and 9' running over guiderollers (Z. Thesefelts feed the paper into the presses. The laying felt f of the secondpress 72 is so arranged that it moves the paper go up to the level ofthe guide-rollers 72 and i intended for the guiding. The machine mindertakes off at A the arriving paper and passes it over the guide rollers hand 2', and from there downward into the press 0. With this mode ofguiding the paper it follows the way, from above to below, which, onaccount of its own weight, it is forced to follow, so that it is safeagainst tearing. In this way the attendance of the turning is alsogreatly facilitated. The difliculties, which moreover the taking off ofthe paper from the roller 0 ofiers, are here entirely removed, for themachine minder has free access to this-roller at the place marked withB, and can effect without any difficulties the guiding over the guiderollers 70 and Z,

For facilitating the forward movement of the paper to the drivingapparatus m, the drying felt n is moved forward in the usual manner,until it is under the raising felt press 0. The paper which has passedaround the rollers is and Z is, on being guided upward, seized by thedrying felt and brought 1 in front of the guide-roller 0, so that themachine minder can easily effect by hand the transmission upon theroller.

In the form of construction illustrated in Fig. 2 the transporting feltf of the laying press Z) is moved forward until it is above the raisingpress 0, so that the guide-roller h is vertically above the raisingpress. The arriving paper 79 hangs down from the guideroller h and movesin consequence of its own weight vertically downward. Arrived at the thelower end, the paper passes upon a guide roller 9 arranged close abovethe felt g and which deposits the paper upon this felt, whereupon it isconveyed by the latter into the press.

If the wet presses are constructed in such a way that the raising feltpress c is placed between two laying felt presses a and b, the layingfelt of the laying press following the raising press is guided in thesame manner as the drying felt n.

What we claim as our invention and desire to secure by United StatesLetters Pat ent is 1. In combination with the raising felt press c, theguide rollers situated vertically above said press and adapted to berotated by the weight of the paper, a transporting felt and means forsupporting the paper off said felt on its way to the guide roller.

2. In combination with the raising felt press 0, the transporting feltg, a guide roller located vertically above the press c and adapted to berotated by the weight of the paper a transporting felt f, means forraising the paper off said felt f on its way to the guide roller, and asecond guide roller Q located in front of the press c and justabove thefelt g and adapted to receive the paper from the first guide roller anddeposit it upon the felt g.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
